Universal type multi-grid-line battery piece test apparatus

The invention relates to a universal type multi-grid-line battery piece test apparatus. The universal type multi-grid-line battery piece test apparatus is characterized by comprising a rectangular copper substrate (10), wherein two parallel U-shaped openings (00) are formed in the middle of the left side edge of the copper substrate (10); two parallel U-shaped openings (00) are also formed in the middle of the right side edge of the copper substrate (10); and a first group of battery piece positioning long grooves (121), a second group of battery piece positioning long grooves (122), a third group of battery piece positioning long grooves (123) and a fourth group of battery piece positioning long grooves (124) are formed in the front side edge and the back side edge of the copper substrate (10). The invention provides the universal test platform applicable to the existing multi-grid-line battery pieces of all dimensions and sizes; the problems of inaccurate positioning and complex switching of the main grid lines in the power and EL testing of the battery pieces are solved; and instead, accurate positioning and convenient switching of the main grid lines in the power and EL testing of the battery pieces can be realized.
